The Coast Guard operates a diverse complement of servicing vessels to service aids to navigation. Of these, the fleet of 28 WLB's (seagoing buoy tenders) is the largest and oldest. Over 40 years old, these vessels are well beyond the end of their economics service life. The replacement process is complex and new vessels will not start to come into service until the mid 1990's. Fourteen of the WLB's underwent a major renovation to prolong their service life. A Service Life Extension Project (SLEP) was begun to prolong the service life of the remainder of the fleet. Four vessels have completed the SLEP and two more are in process. However, a recent decision by the Coast Guard to limit the SLEP to a total of nine vessels has resulted in a projected fleet reducton to 23 vessels. This analysis determines the most effective home ports for this remaining WLB fleet. The most effective ports comprise those from which WLB's can service the entire current workload with a minimum of increased resource time dedicated by the fleet.
